1 Claim. (Cl. 160-34) This invention relates to an improved supportingbracket for the cornice board of a Venetian blind assembly.

An object is to provide a supporting bracket for the cornice board of aVenetian blind assembly which bracket is adapted to be mounted upon theside walls of the conventional upwardly open trough-shaped head boxcommonly employed to house the Venetian blind supporting and operatingmechanism.

A further object is to provide a supporting bracket of the characterdescribed which is simple, inexpensive, capable of being attached to ordetached from an upwardly open trough-shaped head box, and which willsecurely maintain its position upon the head box and is so constructedas to be readily adjustable with respect to the head box and is adaptedto support a cornice board structure.

Another object is to provide a supporting bracket of the characterdescribed which is readily adjustable toward and away from the head boxto support the cornice board at desired positions outwardly beyond thehead box. In this connection the bracket is so built that it may bequickly and easily accommodated to provide for the support of thecornice board at desired positions spaced outwardly beyond the head box.

Another meritorious feature of this improved bracket assembly is that itis so built that it may be readily accommodated to be mounted upon headboxes of different sizes. The bracket assembly is therefore capable ofuse under widely varying conditions and it is therefore not necessary toprovide different bracket assemblies for different sized head boxes ordifferent conditions of use.

Other objects, advantages and meritorious features Will more fullyappear in the following description, appended claim and accompanyingdrawings.

In the drawings:

Fig. l is a perspective of the improved cornice board supporting bracketmounted upon the head box structure;

Fig. 2 is a transverse sectional View through the structure of Fig. 1taken on the line 2-2 thereof but showing a cornice board mountedthereon and the traverse rod of a drape mounted thereon;

Fig. 3 is a fragmentary sectional view taken on the line 3 3 of Fig. 2;

Fig. 4 is a perspective of a mounting plate which forms a part of thebracket assembly; and

Fig. 5 is a perspective of the cornice board supporting member of thebracket assembly.

ln the figures of the drawing the head box is indicated by the numeral10. It is shown as provided with a pair of spaced upstanding parallelwalls 12. These walls terminate at their upper edges in complementaryinturned marginal portions 14. The head box itself is a troughshapedupwardly open member which houses the operating and supporting mechanismof a venetian blind assembly. The Venetian blind structure and itsoperating and supporting mechanism is not shown because it forms no partof the instant invention. The head box itself 2,752,991 Patented July 3,1956 ICC may be supported at its ends by suitable brackets or the likewhich may be secured to the window jambs. These, too, form no part ofthe invention herein disclosed.

This invention relates to the bracket assembly which carries the corniceboard and the traverse rod for the drapes. In Fig. 2 a cornice board ofconventional construction is indicated by the numeral 16. A traverse rodis indicated by the numeral 18. A drape is indicated by the numeral 20.The cornice `board is so constructed that it is adapted to be mountedupon lugs 22 at the outer edge of the cornice board, as shown in Fig. 2.The traverse rod is adapted to be mounted Within a hook 24, as shown inFig. 2.

The bracket assembly comprises two cooperating elements. There is amounting plate indicated by the numeral 26 and an angular cornice boardsupporting member indicated by the numeral 28.

The mounting plate is shown in perspective in Fig. 4. It is shown in usein Figs. 1 and 2. lt comprises a flat plate-like portion having itsedges along opposite sides rolled over as at 30 forming complementaryopposed inturned margins which serve as a guideway spaced above theplane of the plate. The opposite end portions of the plate are shown inFig. 4 as exhibiting a plurality of substantially parallel weakenedlines of severance 32 which extend transversely across the plate.

These weakened lines of severance are provided in order that endsections may be broken off along such lines to provide a plate of theproper length to be snugly receivable between the side walls 12 of ahead box, as shown particularly in Figs. 1 and 2. The opposite ends ofthe plate engage the opposite side walls of the head box underneath therolled over margins 14 of said side walls. Such side walls of the headbox are tensioned inwardly so as to exert a pressure upon the oppositeends of the plate holding the same snugly While permitting insertion andremoval of the plate with respect to the head box and adjustment of theplate linearly of the head box.

The cornice board supporting member 28 is L-shaped in cross section andhas one leg 34 which constitutes a slide portion. The other leg is theone lthat is engaged by the cornice board and the traverse rod, asheretofore described. The slide portion 34 has a width to be readilyreceivable, as shown particularly in Figs. 1 and 3, between the inwardlyturned margins 30 of the mounting plate for slidable adjustmenttherethrough. Such inturned margins of the mounting plate constitute aguide- Way for the slide portion 34.

The slide portion 34 rides over the upper edges of the side walls of thehead box, as shown particularly in Figs. 1 and 2. It is supported uponthe upper edges of said side walls 12. It is held by such side wallsupwardly against the inturned portions 30 of the mounting plate. Theseinturned portions 30 bear resiliently against the slide portion 34 sothat it is held frictionally at that position to which it may beadjusted within the guideway of the mounting plate. The slide portion 34is also provided With a plurality of substantially parallel spaced apartweakened lines of cleavage along which portions may be broken therefromto determine the length of the slide portion 34. Through breaking offportions along the weakened lines 36 the slide portion may be providedin different lengths so that the cornice board supporting part 28 may bepositioned at the desired spacing away from the head box.

As heretofore set forth, not only is the mounting plate adapted to beaccommodated to be received between side Walls of head boxes ofdifferent widths, but the slide portion 34 is adapted to be accommodatedto dispose the cornice board support proper at different positions ofspacing with respect to the head box. The bracket assembly is thereforeapplicable to different head boxes and dierent positions of use and llsa substantial universal purpose in the field.

What I claim is: i,

A support for a cornice board of a Venetian blind assembly consisting ofa trough-shaped head box having side walls tensioned toward each otherand provided with edge portions rolled over inwardly into the head box,a mounting plate disposed for slidable movement within the head box,said mounting plate consisting of a main ilat section and opposed sidemarginal portions rolled upwardly over the plate defining opposedcomplementary guide channels, said flat section of said plate having apredetermined length and being disposed for slidable movement within thehead box with the flat end portions of said flat section extendingunderneath and in contact with said rolled over edge portions to preventupward movement of said mounting plate relative to said head box, theends of said at section extending into abutting contact with the sideWalls of the box tensioning said side Walls outwardly and frictionallyinhibiting sliding movement along said box, said guide channelsextending transversely of the box between said rolled over edge portionsand being tensioned yieldingly toward the at portion of said plate, anL-shaped cornice board supporting member having a first leg adapted tosupport a cornice board and having a second leg of predetermined lengthwith its upper surface in contact only with said guide channels and itslower surface in Contact only with the upper surfaces of the rolled overedge portions of said head box to prevent downward movement of saidmounting plate relative to said head box, said guide channels having adepth not greater than the vertical height of said rolled over edgeportions plus the thickness of said second leg to insure abuttingengagement of the upper surface of said mounting plate with the lowersurfaces of said edge portions of said box to thereby clamp said secondleg of said mounting plate in a predetermined position relative to saidhead box.
